Description

AREA

At least one embodiment relates to refrigeration systems, including systems and methods of operating those refrigeration systems. In at least one embodiment, such a cooling system may be used in a data center that includes one or more racks or computer servers.

BACKGROUND ART

Data center cooling systems use fans to circulate air through server components. Certain supercomputers or other high-performance computing systems may use water or other cooling systems instead of air cooling systems to move heat away from the data center's server components or racks to an area outside the data center. The cooling systems may include a chiller within the data center area, which may include an area outside of the data center itself. Further, the area external to the data center may include a cooling tower or other external heat exchanger that receives heated coolant from the data center and rejects the heat to the environment (or an external cooling medium) through forced air or other means. The cooled coolant is recirculated back into the data center. The chiller and the cooling tower together form a refrigeration system.

In at least one embodiment, a liquid cooling system can be used for moderate or heavy cooling requirements. In at least one embodiment, high cooling requirements are economically met by local immersion cooling. In at least one embodiment, these different cooling requirements also reflect different thermal characteristics of a data center. In at least one embodiment, the heat generated by these components, servers, and racks is cumulatively referred to as a thermal attribute or a cooling requirement since the cooling requirement must fully address a thermal attribute.

In at least one embodiment, a liquid cooling system for a data center is disclosed.

In at least one embodiment, a number of the items in a plurality is at least two, but may be more, either where explicitly stated or where the context indicates. Unless otherwise stated or otherwise clear from the context, the phrase “based on” means “based at least in part on” and not “based solely on”.

Operations of processes described herein may be performed in any suitable order, unless otherwise noted herein or the context clearly dictates otherwise. In at least one embodiment, a process, such as the processes described herein (or variations and/or combinations thereof), is performed under the control of one or more computer systems configured with executable instructions and is defined as code (e.g., .executable instructions, one or more computer programs, or one or more applications) executing together on one or more processors, implemented by hardware or combinations thereof. In at least one embodiment, code is stored on a computer-readable storage medium. In one embodiment, in the form of a computer program comprising a plurality of instructions executable by one or more processors. In at least one embodiment, a computer-readable storage medium is a non-transitory computer-readable storage medium that excludes transient signals (e.g., propagating transient electrical or electromagnetic transmission) but not transient data storage circuitry (e.g., buffers, cache, and queues) within includes transient signal transceivers. In at least one embodiment, the code (e.g., executable code or source code) is stored on a set of one or more non-transitory computer-readable storage media storing executable instructions (or other storage for storing executable instructions) that upon execution (i.e., as a result of execution) by one or more processors of a computer system, causing the computer system to perform operations described herein. A set of non-transitory computer-readable storage media, in at least one embodiment, includes a plurality of non-transitory computer-readable storage media and one or more of each non-transitory storage media of multiple non-transitory computer-readable storage media lacks all code, while multiple non-transitory computer-readable storage media collectively store all code. In at least one embodiment, the executable instructions are executed such that different instructions are executed by different processors - in at least one embodiment, a non-transitory computer-readable storage medium stores instructions and a main central processing unit ("CPU") executes some of the instructions, while a graphics processing unit ( "GPU") executes other instructions. In at least one embodiment, different components of a computer system have separate processors, and different processors execute different subsets of instructions.

Rather, in some of the at least one embodiment, "connected" or "coupled" may be used to indicate that two or more elements are in direct or indirect physical or electrical contact with one another. "Coupled" may also mean that two or more elements are not in direct contact with one another, but nevertheless co-operate or interact with one another.

Unless expressly stated otherwise, it is understood that terms such as "processing", "computing", "calculating", "determining" or the like throughout the description refer to actions and/or processes of a computer or computing system or a similar electronic computing devices that manipulate and/or convert data represented as physical, such as electronic, quantities within the registers and/or memories of the computing system into other data represented in a similar manner as physical quantities within the memories, registers or other such information storage, transmission or display devices of the computing system.

Similarly, the term "processor" may refer to any device or portion of a device that processes electronic data from registers and/or memory and converts that electronic data into other electronic data stored in registers and/or can be stored in memory. As a non-limiting of the at least one embodiment, the "processor" can be a CPU or a GPU. A "computing platform" may include one or more processors. As used herein, "software" processes may include, for example, software and/or hardware entities that perform work over time, such as tasks, threads, and intelligent agents. Also, each process can refer to multiple processes to execute instructions sequentially or in parallel, continuously or intermittently. The terms "system" and "method" are used interchangeably herein in the sense that a system may embody one or more methods and the methods may be considered a system.

As used herein, reference may be made to acquiring, capturing, receiving, or inputting analog or digital data to a subsystem, computer system, or computer-implemented machine. In at least one embodiment, the process of acquiring, capturing, receiving, or inputting analog and digital data may be accomplished in a variety of ways, such as receiving data as a parameter of a function call or an application programming interface call. In some implementations, the process of acquiring, capturing, receiving, or inputting analog or digital data can be accomplished by communicating data over a serial or parallel interface. In another implementation, the process of acquiring, capturing, receiving, or inputting analog or digital data may be accomplished by transmitting data over a computer network from the providing entity to the collecting entity. It can also refer to providing, outputting, transmitting, broadcasting or displaying analog or digital data. In various of the at least one embodiment, the process of providing, outputting, transmitting, sending, or representing analog or digital data may be performed by transferring data as input or output parameters of a function call, parameters of an application programming interface, or an interprocess communication mechanism.

Although the foregoing discussion sets forth some of the at least one embodiment with implementations of the described techniques, other architectures may also be used to implement the described functionality and are intended to be within the scope of this disclosure. Additionally, although specific distributions of responsibilities are defined above for discussion purposes, various roles and responsibilities could be distributed and divided differently depending on the circumstances.

Further, while the subject matter has been described in language specific to structural features and/or method acts, it is to be understood that the subject matter claimed in the appended claims is not necessarily limited to the specific features or acts described. Rather, specific features and acts are disclosed as example forms of implementing the claims.
